Description

Edwards KIR-OSHD Intelligent Smoke and Heat Detector

Overview
The Edwards Intelligent Optica Series KIR-OSHD smoke detector brings advanced optical (photoelectric) sensing technology. To a practical design that increases efficiency, saves installation time, and cuts costs. And extends life safety and property protection capabilities.
The KIR-OSHD provides an optical smoke sensor and a rate-of-rise heat sensor with a fixed temperature setting.
Together these sensors efficiently detect smoldering fires and fast flaming fires.
Like all Edwards Intelligent Optica Series detectors, the KIR-OSHD – an intelligent device that gathers analog information from multiple optical sensors. Converting this data into digital signals. Utilizing
dual optical wavelengths combined with multiple detection angles. The KIR-OSHD differentiates particles – not representative of actual smoke. Particle data – input into digital filters which feed a series of ratios removing signal patterns. The detector’s onboard microprocessor measures and analyzes all optical sensors. Readings and compares this information to preprogrammed settings.

The KIR-OSHD detects particles from a wide range of combustion sources. Thanks to its high-performance reflective response technology. The smoke sensor responds quickly and reliably to a wide range of fire types. Fast and slow-burning fires fueled by combustibles – typically found in modern multi-use buildings.
Heat detection
KIR-OSHD’s onboard rate-of-rise heat sensor provides a 15°F (9 °C) per minute function for detection of fast-developing fire.  Providing a 135 °F (57.2 °C) fixed detection
threshold. The heat sensors monitor the temperature of the air and determine whether an alarm should – initiated.
Installation
Edwards Intelligent Series detector bases mount to North American 1-gang boxes. 3-1/2 inch or 4-inch octagon boxes, and 4-inch square electrical boxes 1-1/2 inches (38 mm) deep. They mount to European BESA and 1-gang boxes with 60.3 mm fixing centers. See mounting base installation and wiring for more information.
